Answer : 110 degree

To find angle 1 , we apply outside angle theorem Lets name each point Measurement of arc EF=280 degrees

Measurement of arc GH = 60

Angle D = angle 1

Please refer to the theorem attached below

$angle D = \frac{arc(EF)-arc(GH)}{2}$

Now we plug in the values

$angle 1 = \frac{280-60}{2}$

angle 1 = 110

Measurement of angle 1 = 110 degrees

Answer:

$20.63 if you tip on the pre-tax amount

Step-by-step explanation:

You pay $12.99 for the pizza, plus the 8% tax on the pizza, plus the 20% tip of the cost of the pizza, so if you tip on the pre-tax amount, you pay

$12.99(0.08) = $1.04 in sales tax

$12.99(0.2) = $2.60 for the tip

and $4 delivery charge,

so you pay a total of

$12.99 + $1.04 + $2.60 + $4 = $20.63

Answer:

135

Step-by-step explanation:

The given expression is

$\frac{2 {x}^{2} }{x} +x(100 - 15x)$

From the question, x=5

So,by substitution,we obtain

$=\frac{2({5}^{2})}{5} +5(100 - 15(5))$

$=\frac{2(25)}{5} +5(100 - 75))$

$=2(5)+5(25)$

$= 10+125$

$= 135$

Hence the answer is 135
